Not so wonderful Remote services - especially during our Pandemic!!!

Hi, I am really upset with your remote services... I sold my phone in order to purchase a new one.Now, when I download the Capitec Banking App, it's asking me to open the old App to verify my email address.How on earth do you think is this possible? Who thought this will be a good idea? What if a phone gets lost or ******? How do you retrieve your access to the app?I have tons of accounts that I am use to paying via my cellphone... now I am late on EVERY payment and this will be updates on my Credit Score? Do you even know the implications of this? I cannot go to the bank, because I am a full time worker and I have just returned from leave. Can I get any assistance whereby my app will work again when I install it on my phone? I would gladly consider moving my bank account! *** - I have phoned your customer services, it was useless!!!!
